The kiosks sound ridiculous--stand in line to get a FP+ so you don't have to stand in line later?!? This certainly isn't an improvement over the old system. If I were WDW, I would have integrated a bar scanner into
MDE. They could have placed signs in multiple locations throughout the parks for easy access. Guests could go over to one of many signs with FP+ rides listed with their barcodes, scan the barcode associated with a desired ride and step away while the system looked up available times, then choose a time that was returned as available. No need to have people standing in line waiting for a kiosk.
WDW could give on-site guests the advantage of pre-booking 3 FP+ and then availing themselves of the scanned FP+ in park.
